Study summary

Bone and joint infection (BJI) are bacterial infections that can occur after surgery (nosocomial infections) or de novo. They constitute a public health problem in Western Countries . These infections are often difficult to treat, with a high rate of re-hospitalizations (19.5%) caused by relapses or recurrences. The treatment of Bone and joint infection can be surgical and / or pharmacological . Drug treatment is based on the use of parenteral and / or oral antibiotics. It is a curative therapy in most cases, with a prolonged duration ranging from 6 weeks to several months depending on the lesions .

Medication adherence, is a patients' behavior defined as drug intake with optimal attendance and regularity, as prescribed and explained by the physician. It is a key factor in the success of any drug therapy, as drugs don't work in patients who don't take them..

To the knowledge of investigators, there are no published data on the adherence to antibiotic therapy in patients treated for Bone and joint infection. In addition to its prolonged duration, the antibiotic treatment of the Osteoarticular Infections may require several daily drug intakes and may be responsible for severe adverse effects, these three factors being known to adversely affect adherence.

Prevalence, adherence patterns over time and determinants of adherence in this patient population are not known. Currently, drug adherence is not routinely evaluated and is not considered in the treatment of Bone and joint infection in the Regional Center for Complex Bone and joint infection of the investigators.

A specific study evaluating adherence to antibiotic therapy in patients treated for Bone and joint infection appears to be justified.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • Patients with osteoarticular infection

    To evaluate drug adherence to oral antibiotic therapy in patients treated for bone and joint infection for a minimum expected duration of 6 weeks.

    Other: Drug adherence questionnaire

Interventions

  • OtherDrug adherence questionnaire

    Adherence to oral antibiotic therapy will be assessed by means of a questionnaire adapted from the French standardized self-assessment questionnaire of Girerd et al. This questionnaire has six questions, each question being associated with a score. Patient's drug adherence is classified into three groups based on the total score: of high, moderate and poor adherence. The questionnaire will be carried by a phone call to the patient.

06

What researchers measure

Primary outcomes

  1. Proportion of patients with high, moderate and poor adherence

    Adherence will be assessed using a questionnaire adapted from the questionnaire of Girerd et al. with 6 questions. Adherence will be assessed during the antibiotic treatment, after 6 weeks of therapy in all patients included. For the included patients still treated at 3 months, it will be evaluated a second time at 3 months.

    Time frame: 3 months
